ios - How to have a dynamic List of Views using SwiftUI

I can do a static List like

List {
   View1()
   View2()
}

But how do i make a dynamic list of elements from an array? I tried the following but got error: Closure containing control flow statement cannot be used with function builder 'ViewBuilder'

    let elements: [Any] = [View1.self, View2.self]

    List {
       ForEach(0..<elements.count) { index in
          if let _ = elements[index] as? View1 {
             View1()
          } else {
             View2()
          }
    }
}

Is there any work around for this? What I am trying to accomplish is a List contaning dynamic set of elements that are not statically entered.

Looks like the answer was related to wrapping my view inside of AnyView

struct ContentView : View {
    var myTypes: [Any] = [View1.self, View2.self]
    var body: some View {
        List {
            ForEach(0..<myTypes.count) { index in
                self.buildView(types: self.myTypes, index: index)
            }
        }
    }
    
    func buildView(types: [Any], index: Int) -> AnyView {
        switch types[index].self {
           case is View1.Type: return AnyView( View1() )
           case is View2.Type: return AnyView( View2() )
           default: return AnyView(EmptyView())
        }
    }
}

With this, i can now get view-data from a server and compose them. Also, they are only instanced when needed.
